The now-17-year-old Hannah Dakota Fanning became famous as the darling young actress starring with Sean Penn in "I Am Sam." She has since grown into a teen star with recent major roles in "The Runaways" and in "The Twilight Saga" series. Her little (though now taller than Dakota) 13-year-old sister, Elle, was also in "I Am Sam"  though at the time she was only 3. Since then, she's had roles in numerous films, including in the festival fave "Phoebe in Wonderland" and most recently in J.J. Abrams' "Super 8."
